Hi, I'm seriously considering redeeming miles for J in December. It would be very grateful if somebody can help me to do a flight load check on:

CX881 & CX883 - both 8 & 15 December

I'm currently on a waitlist for Y on 15 Dec. I asked a ground crew in HKG about the availably on 15 Dec and she said that I have very minimum chances of successfully redeeming a ticket of both CX881 and 883 in every class even for being a MPO Go. Since it is my birthday I really wish I can travel on CX on that day.

P.S.: I've checked 8 Dec and there are seats available in Choice award, but not in Standard award (being waitlisted). How high is the chances if I can redeem in Standard award (as MPO Go)?
Much appreciated.
